GATE-OPENER.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed June 15, 1906. Serial No. 321,934.

To alliuhom it may concern.-

Be it known that I, ELDRIDGE T. HILL, a citizen of the United States,residing at Murfreesboro, in the county of Rutherford and State ofTennessee, have invented certain new and useful Improvements inGate-Openers and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in devices foropening sliding gates, and comprises a swinging yoke carrying anantifriction-wheel which is designed to engage parallel rods positionedtransversely upon the gate and against which the roller is adapted tobear as the yoke is raised and lowered, whereby the gate may be openedor closed.

The invention comprises various details of construction and combinationsand arrang ments of parts which will be hereinafter in 1 described andthen specifically defined in the appended claim.

I illustrate my invention in nying drawings, in which- Figure 1 is aside elevation of my gate, showing the same in solid lines closed and inthe accompadotted lines opened; and Fig. 2 is a sectional viewlongitudinally through the gate, showing in top elevation the yoke.

Reference now being had to the details of the drawings by letter, A Adesignate posts between which a gate is adapted to slide, a suitablecross-piece A ends of the posts, and which cross-piece is notched, as atA forming a guide for the gate as it is opened and closed.

B B designate posts supporting a track B, upon which the grooved sheavesC, journaled at the upper en s of the end pieces D of the gate, travel.Fixed to the posts A is a crosspiece E, upon which the levers F arepivotally mounted, having ropes F at their outer ends for convenience intilting the levers.

The gate comprises a series of longitudinal strips H, fastened to thevertical pieces I,

connecting the lowerv and between the inner ends of said strips a spaceintervenes in which the parallel bars K are disposed, the ends of saidbars being fastened to top and bottom strips J of the gate and spacedapart.

N designates a yoke the rear end of which is pivotally mounted upon rods1 ,fixed to said posts A, and in the ends of the arms of said yokes ismounted a shaft 0, which extends through the space intermediate saidrods K, and R designates a grooved sheave journaled upon the shaft 0 andadapted to coact with one or the other of said rods K, accordingly asone orthe other is frictionally engaged by the sheave in theact ofopening or closing the gate.

The inner ends of the levers F are pivotally connected together by meansof a link F and TT designate bars which are pivotally connected each toone of said levers and their lower ends pivoted to the upper ends of thebars T which are in turn pivotally connected to the arms of said yoke.

The operation of my gate will be readily understood and is as follows:The gate being closed and should it be desired to open the same by aperson approaching from either side thereof one or the other of thelevers F may be tilted, causing the yoke N to be raised, and as thesheave carried thereby bears frictionally against the rod nearest therear end of the gate the latter will be caused to, move backward as theyoke carrying the sheave rises toward a vertical position. A reversemovement of one of the levers F will cause the yoke to be forceddownward again, and as the sheave carried thereby frictionally engagesthe rod nearest the front end of the gate and a pressure applied theretothe gate will move back into a closed position.

What I claim is- A hand-opener for gates, comprising in combination witha sliding gate, bars connecting the top and bottom horizontal stripsthereof, and spaced apart, posts between which the gate is adapted tomove, a yoke, having an arm of the latter disposed on either side of thegate, each arm being pivoted to one of said posts, a pivot-pin mountedin the other ends of said arms, a sheave journaled on said pin, andbetween said rods,

and against which the sheave is designed to upper edge, in which thegate is guided, as

contact, as the %'ate is opened or closed, pivset forth. 1o otaloperatingevers, link connections be- In testimony whereof I hereuntoaffiX my tween the inner ends of the latter, a bar pivsignature in thepresence of two witnesses. otally connected to each arm of the yoke,ELDRIDGE T. HILL. links, each connecting one of said bars, withWitnesses:

an operating-lever, a cross-piece fixed to G. S. RIELLEY,

said posts, and having a recess formed in its THos. B. LYTLE.
